Problem with Facebook Messenger (iPhone 4 & iPod Touch Gen 4) with shared photos?

I seem to have a problem with Messenger not showing all my shared photos. This morning, when I went under the info section, it says I have only shared one photo with all my friends, even though I know we have over 250 with some people, so does anyone know what is going on? The app hasn't updated or anything, it just started today.

IPhone 5 is doing the same, it's a real pain.

It's not just you and I don't think it's restricted to any version of the iPhone. All but one of my shared photos have gone AWOL too although they're still in the message thread.
